Mattis exit not likely to damage Canada-U.S. security ties: experts

U.S. Defense Secretary Jim Mattis’ decision to resign creates a void for Canada, says former Defence Minister Peter MacKay, because of Mattis’s deep understanding of Canada’s role in joint NATO and UN missions and good ties with Canadian security officials.

His years of experience in the U.S. military and on-the-ground understanding of the parts of the world where he served as a Marine general, particularly in Iraq and Afghanistan, are “virtually irreplaceable,” MacKay said.

After serving for two years at the top of the U.S. military machine, Mattis announced Thursday that he’d resign as of the end of February, in a move widely seen as a rebuke of Trump’s decision to abrupt withdraw U.S. troops from Syria.

The retired general has been considered a moderating influence on Trump over his last two years as Pentagon chief, which is why concerns have been raised by ally nations about how his departure could affect U.S. security and foreign policy.

These concerns are particularly focused on America’s role in the NATO transatlantic alliance after Trump said this week that not only will the U.S. military pull out of Syria, but the number of U.S. troops will also be cut in half in Afghanistan, where the U.S. is part of the NATO-led joint mission Operation Resolute Support.

“In spite of the moniker ‘Mad Dog Mattis’ he was anything but. He was a highly intelligent, highly rational guy and he saw first-hand the integration of defence, diplomacy, development that Canada was doing and was very full of praise and admiration for that,” MacKay said.

Mattis’s departure is even more keenly felt in light of the departures of H.R. McMaster and John Kelly, who U.S. President Donald Trump also appointed to serve in his administration, MacKay added. McMaster was an army general who was Trump’s national-security adviser for a year; Kelly is a retired Marine general who served as secretary of homeland security and then Trump’s chief of staff.

McMaster resigned last April; Kelly is to leave the White House at the end of this year.

“Jim Mattis and the others have and feel an abiding respect for Canada and our role in NATO and in NORAD, for our niche capabilities, what we were able to do along with others in the coalition, both the UN and NATO coalition in Afghanistan, our support role in other missions,” MacKay said. “That, too, is in some jeopardy depending on who replaces Gen. Mattis.”
